Description

50Watt

1/16 Brick

Single Output

The RPA50S is a low cost 50W DC/DC converter in industry standard 1/16th brick format

(33mm x 23mm) and pinning. The 4:1 input range covers 24V, 28V or 48V nominal input voltages

and the output voltage options are 3.3V, 5V or 12V with +10%/-20% trim. Output power is 40W from

18-75V or 50W from 36-75V. The efﬁciency is particularly high (88-91%) to permit full load operation

from -40°C up to +54°C ambient temperature with only free air convection and up to 85°C with forced

air cooling. The isolation voltage is 2.25kVDC/1 minute (basic insulation grade). Applications include

demanding industrial power supplies, telecom and PoE circuits.
